MATTRESS FRAME.

Specification of Letters Patent. Pat-embed bruine 13, 1922..

Application filed August 19, 193.9. Serial No. 318,509.

To all whom t may concern minion of Canada, haveinvented an Improvement in Mattress Frames, of which the following description, in connection with the accompanying drawing, is aspeciiication, like characters on Vthe drawing representing like parts.

This invention relates lto mattress frames and particularly to the manner of connecting the side rails and the end rails. In the manufacture of mattress frames it is usual to provide a corner fastening construction at each end ofthe Side rail for connecting the side rail to the end rail, such corner fastening construction being so arranged that the end rail is supported above the side rail and frequently slightly beyond the end thereof.

It is the object of my present invention to provide a novel corner fastening which can be made of sheet metal without the loss of any material; which has all the necessary strength to support the end rail; which is light in weight, and which is so constructed that when it is used with tubular end rails and Side rails it operates not only to connect these rails, but also to close the ends of the tubes.

l.In order to give an understanding of my invention, I have illustrated in the drawings some selected embodiments thereof which will now be described, after which the novel features will be pointed out in the appended claims.` y

Fig. l is a perspective view of a corner of a mattress frame embodying my invention and having rectangular tubular side and end rails;

inclined to the bottom edge.

In the drawings I have illustrated one corner only of a mattress frame as this is sufficient to give an understanding of the invention.

, My improved corner fastening may be used in mattress frames having side and end rails of various shapes.

I have illustrated herein the invention as it would be embodied in mattress frames having tubular side and end rails, and in Figs. l to 6 I vhave shown a' mattress frame in which the tubular side and end rails are rectangular in cross-section and in Figs. 'T and 8 I have illustrated a mattress frame in which the tubular side rails are circular in cross-section.`

` Referring to Figs. l to 6, l indicates the end of a 'tubular side rail and 2 indicates one end of' a tubular end rail, bothof said tubular rails beingrectangular in cross-section so that each presents opposite fiat sides.

The corner fastening is indicated generally at 3- and it is made from a sheet metal blank which will preferably have the shape shown in Fig. 4, said blank being narrower at one end' than at the other and having one side edge l() atright angles to the bottom edge ll and having the other side edge l2 This sheet metal blank is bent transversely along the dotted line G so as to provide the lip or iiange portion 5 which extends at right angles to the body and is also bent along the inclined dotted. line 7 so that the portion 8 thereof will stand at right angles to the body of the blank. v l i In securing the corner fastening to the railsl and 2 said fastening is placed against the end of the rail 2 with vthe bent-over portion 5 overlying the top of the rail, as shown in Fig. l, so that the end of the rail is'closed by said fastening, and the latter is then secured to the rail 2 either by means of rivets 9 which extend through the bent-over portion 5 andthe tubular endrail, as shown in Fig. 2, or by welding the portion 5 to the end rail. The lower end of the corner fastening is secured to the end vof the side rail l in the manner` shown in Figs. l and 3, that is, said side rail yand corner fastening are yassembled so/that the lower end of the corner fastening overlies the outer face of the side rail and the end of the side rail abuts against :the portion 8 of the fastening,lsai d portion'being made wide enough to completely cover the end of the side rail. The

.ses

side rail. The corner fastening thus operates to close completely the ends of both the tubular rails 1 and 2.

The use of tubular rails is advantageous because they are light and yet strong, and by means of them a light; weight mattress frame can be produced, but where tubular rails are used it is important that the ends should be closed, for otherwise open spaces are provided for harboring vermin. The construction herein shown has the advantage that it enables the use of tubular side and end rails and at the same time provides av construction by which the ends of the rails are closed, thus eliminating -any possible cracks or crevices in which vermin might gather.

Since the side 12 and the line 7 along which the corner fastening is bent are both inclined to ,the base 11, the result will be that the end rail 2 will be situated slightly beyond the end of the side rail 1 which is a desideratum in ymattress frames. Furthermore, in the completed mattress frame the lower edge 141 of the portion S-is longer than the width of the side rail 1 and hence said vportion extends inwardly beyond the side rail, thus making a desirable added support to rest on the' bed frame.

In Figs. 7 and 8.1 have illustrated my in veution as it might be applied to a mattress frame in which the tubular side rail is cylin drical in shape and the tubular end rail is rectangular in shape. In this construc- V tion the fastening which is indicated at 30 is secured to the rectangular end rail 2 in the same manner as illustrated 1n Figs. 1 to 6. In Figs. 7 and 8, however, the side rail 31 is shown as circular in cross section,

and in this embodiment the fastening 30 will be formed from a blank shown in Fig. 9 which is bent along the dotted line 32 so as to provide the wing portion 33 that stands at right angles to the main portion 30. The lower end of the portion 30 overlies the side of the side rail 31 and is curved to iit lthe periphery of said side rail, said lower end being welded or riveted to the side rail. The bottom edge of the blank 30 is shaped so that when the wing 33 is bent into right-angular position relative to the body of the cornery fastening, the portion 34 of the lower edge of said wing will follow the periphery of the side rail 31 and the portion 35 of said lower edge will extend tangential thereto and substantially parallel to the end rail 2. rlhis wing 33 is of suitable dimensions so that it entirely covers the end of the side rail 31 and thus in this embodiment of my invention also the corner fastening is constructed to close the end of the rails 31 `and 2. in this embodiment also the' corner fastening has a backward inclinationrelative to the side rail 31 so that the end rail will be situated beyond the end -of the side rail and the end of the side rail is cut at an angle to fit against the inclined wing 33, as best seen vin Fig. 7. A

rThe use of tubular side and end f rails which are rectangular in cross-sectional area has the advantage that tubes of lighter weight can be used without sacricing neces.- sary strength. ln the end rail, the strain comes in a horizontal direction, and by plac ing` this end rail with the `longer diameter horizontally, a rail having a relatively small vertical dimension can be employedwithout sacriiicing any necessary strength. The strains on the sidel rail are in a vertical di with their longer diametersin a vertical direction the necessary strength is secured,

even though the side rail has a relatively small horizontal dimension.

l claim: 1. ln mattress frame, the combination with a flat-sided tubular end rail, of a flatsided tubular side rail, and a corner fastening` member made of sheet metal which is bent to form three portions, each situated at right angles to the other, oneportion overlying and secured to the side of the end rail, another portion closing the open end of said end rail andv overlying and'being secured to the side of the side rail, and the other portion closing the open end of the p side rail.

2. ln a mattress frame, the combination with a tubular side rail rectangular in ycross section with its longer dimensionin a vertical direetion, of a tubular end rail also rectangular' in cross section but with itslonger dimension in a horizontal direction, and a corner fastening member of sheet metal which is bentto form three portions at right angles to yeach other, one portion being secured to the `side of the side rail and closing the open end of t-he end rail, another portion closing completely the open end of the side rail, and the third portion overlying andbeing secured tothe side of the end rail.

In testimony whereof, 1 have signed my name to this specification.
